from The American Heritage® Dictionary of the English Language, 4th Edition
- n. Any of the nearly colorless cells found in the blood, lymph, and lymphoid tissues, constituting approximately 25 percent of white blood cells and including B cells, which function in humoral immunity, and T cells, which function in cellular immunity.

- n. A type of white blood cell or leukocyte that is divided into two principal groups and a null group; B-lymphocytes, which produce antibodies in the humoral immune response, T-lymphocytes, which participate in the cell-mediated immune response and the null group, which contains natural killer cells, cytotoxic cells that participate in the innate immune response.
from The Century Dictionary and Cyclopedia
- n. A typo of leucocyte found in the blood of all vertebrate animals. It is colored blue or purple with Ehrlich's triple stain, and occurs, in man, normally in the proportion of about 30 per cent. of the entire number of white blood-cells. There are two varieties, the large (11 to 14 microns in diameter), and the small (7.5 microns in diameter), the latter being the more numerous.

A '' 'lymphocyte' '' is a cell that belongs to group of [[white blood cell]] s (i.e., leukocytes), which are a major component of the immune system.
Cellular assays include immunophenotyping of specific cell populations as well as assays for lymphocyte and phagocyte function.
In addition, mitogen or antigen stimulated lymphocyte cultures are performed to measure lymphocyte function.
It is estimated that 30 percentof X-linked lymphoproliferative syndrome (XLP) patients develop lymphoma, an aggressive but usually curable cancer of a type of immune cell known as lymphocyte.
A massive single whole-body exposure of 500 millisieverts could decrease lymphocyte cells in some people, which would compromise their immune systems.
Complete allogeneic hematopoietic chimerism achieved by a combined strategy of in utero hematopoietic stem cell transplantation and postnatal donor lymphocyte infusion.
Cellular: lymphocyte proliferation, flow cytometry
